Use the above link and select your operating system to download your driver.

Clean the registry. Expunge all temp files. & reinstall........sodeep (Use cCleaner)

what happened to the screen
you should always replace your screen with the proper model
sometimes cheaper to gat a new laptop

try uninstalling your sound from device manager , then rebooting ,it will then find new hardware .then you install driver

have you attempted F8 upon the system booting to see if it will allow you to boot into safe mode?
